Porter Mufflers Inc. is introducing its first complete cat-back exhaust system for the 2009-13 Dodge Challenger 5.7 HEMI.

This system is made up of 2.5-inch, mandrel-bent 304 Stainless Steel tubing, uses the original hangers and tailpipe tips, and features Porter's unique "Steel-Pac" mufflers, also in 304 Stainless Steel.

In chassis-dyno testing this system provided a 12+ horsepower increase while dropping 28 pounds of weight from the car, notes Porter. The Porter Mufflers give off a deep, mellow rumble at idle with no drone when in cruising.

"We are quite pleased to offer our first complete exhaust system for the new 5.7 HEMI Challengers and we targeted those customers that want a performance system upgrade that screams at full-throttle but is still mellow at idle and cruising speeds,” says Tom Conlan, owner of Porter Mufflers.
